WILLIAM JOHN PRINGLE, OF BALLTOVN, PENNSYLVANIA.

WELL-DRILLING MACHINE.

.SPECIFIC'ATION forming part of Letters Patent No. 347,377, dated August 17, 1886 Application filed May 15, 1886.

To all whom, it may concern:

Be it known that I, WVILLIAM JOHN PRINGLE, acitizen of the United States, residing at Balltown, in the county of Forest and State of Pennsylvania, have invented a new and useful Improvement in VVell-Drilling Machines, of which the following is a specification.

My invention relates to an improvement in machines for drilling Artesian and oil wells; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a plan view of a portion of a well-drilling machine provided with my improvements. Fig. 2 is an end view. Fig. 3 is a transverse sectional view of the same on line y y of Fig. 1. Fig. 4 is a vertical longitudinal sectional view on line 0c m of Fig. 1. Fig. 5 is a detail view.

A represents the sills of a drilling-machine, andB represents vertical standards, which are secured to the frame of the machine, and have bea'ringblocksO at their upper ends, in which is journaled the usual shaft, D, having the usual friction-wheel, E, for actuating the sandpump reel. V

F represents a vertical standard having its lower end dovetailed to a dovetailed groove, a, made in one of the sills, and G representsa key or wedge, which is inserted between one side of the groove a and the depending dovetailed foot of the standard F, so as to secure the said standard firmly to the sill A.

H represents a shoe, which is provided with longitudinal slots I in its lower sides, and is secured to one ofthesills A opposite thestandard F by means of bolts K, which pass down through the slots I and enter the sill. The shoe is thus made longitudinally adjustable on its sill, as will be very readily understood.v

L represents a lever-arm or standard, the

projecting lugs n,that bear against the sides of 5 the openings at. The said openingisof asufficient size to permit the block N to freely move therein.

0 represents the shaft of the sand-pump reel, one end of which is journaledin an opent ing made in the upper end of the standard F, and the opposite extremity of the said shaftis journaled in the block N. The sand-pumpreel shaft has the usual friction-pulley,P, to bear against the friction-wheel E when thele- 6 ver L is moved rearwardly, so as to impart the motion ofthe said friction-wheel E to the saud-pump reel in the usual way. The sand pump reel is also provided with the usual brake-pulley, R, forstopping the motion of the reel.

By pivoting the plate M to the inner side of the lever L, and locating the block in an opening made in the said plate, and ournaling one end of the sandpiimp-reel shalt in the 7 said block N, it will be readily understood that a universal joint is formed between the said pump-reel shal'tand the lever L, whereby the said lever may be moved to shift the sandpump reel to any desired angle without un- 8 shipping the said reel from the said lever. The shoe H is made movable, as before described, in' order to permit the friction-pulley P to be adjusted, and thereby caused to bear against the friction-wheel E when the lever L 8 is in a vertical position.

Having thus described my invention, I claim- 1. The combination of the pivoted lever L, having the bracket 1, the vertical plate M, g journaled in the said bracket and having the opening m, the block N, secured in the said opening and free to turn therein, and tlie sandpump reel having one end journaled 1n the said block, substantially as described.

2. The combination of the pivoted lever L, and the sand-pu mp reel, and the universal joint connecting one end ot'the said sand-pump reel to the said pivoted lever, for the purpose set forth, substantially as described. 1

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

\VILLIAM JOHN PRINGLE.
